100mA / 50V Digital transistors
(with built-in resistors)
DTC123JM / DTC123JE / DTC123JUA / DTC123JKA
Applications
Inverter, Interface, Driver
Features
1) Built-in bias resistors enable the configuration of an inverter circuit without connecting external input resistors (see the
equivalent circuit).
2) The bias resistors consist of thin-film resistors with complete isolation to allow negative biasing of the input. They also
have the advantage of almost completely eliminating parasitic effects.
3) Only the on / off conditions need to be set for operation, making the device design easy.
Structure
